THOMAS V. ALLIS, OF NEW YORK, N. Y.

METALLIC FENCING.

SPECIFICATION formingpart of Letters Patent No. 486,173, dated November 15, 1892.

Application filed March 7, 1892. SerialNo. 423,971- (No model.) 7

To all whom it may concern:

Be it known that I, THOMAS V. ALLIs, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented new and useful Improvements in Metallic Fencing, of which the following is a specification.

This invention relates to metallic fencingstrips having an ornamental appearance through the configuration of the edges, as hereinafter fully described, reference being made to the accompanying drawings, in which Figure 1 is a side view of a part of a fencing-strip made in accordance with my invention. Fig. 2 is a similar view of the same with an additional feature of construction sometimes employed, and Fig. 3 is an edge view.

Plain flat strips of metal have been crimped edgewise for an ornamental metallic fencing; but the ornamental feature is very slight for lack of sufficient angularity of the edges, it being impossible to make in that manner such acute angles as are necessary for good efiects without material injury to the metal. Instead of crimping the strips I cut acute and preferably V-shaped notches a at intervals along each edge with curved sides forming salient portions 0 between the notches, having curved or rounded edges, said notches being somewhat more in depth than a third of the breadth of the strip and the notches of the respective edges being intermediate to each other and distant from each other along each edge of the strip a space equal to or greater than the width of the notches at their base. This construction makes a thin metal strip that at a short distance has very close resemblance to a rope of twisted fibers or wires. To prevent cracking at the bottom of the notches in case it is desired to strain the strips up taut in long lengths, I make the short slits e thereat so that the converging sides of the notches terminate short of and are confronted by the intact inner walls of the slits, whereon the stresses that would otherwise be concentrated at the bottom are so distributed that cracking is avoidedand as a further contrivance for enhancing the value of this fencing because of its ornamental character I propose to corrugate it sidewise, as represented in Fig.

I claim- 1. The improved metallic fencing strip having V-shaped cut notches along each edge intermediately with alternate salient intervening portions, said salient portions of one edge located opposite the notches in the other edge and. the length of said salient portions being greater than the width of the notches at their base, substantially as described.

2. The improved metallic fencing-strip having V-shaped out notches with rounded corners and alternate salient portions along each edge intermediately, the said salient intervening portions having rounded terminations and located opposite the notches in the other edge, the length of said salient portions being greater than the width of the notches at their base, substantially as described.

3. Theimproved metallic fencing-strip having V-shaped cut notches along each edge intermediately with alternate salient interven-' ing portions, said salient portions of one edge located opposite the notches in the other edge and the length of said salient portions being greater than the width of the notches at their base and said strip being corrugated sidewise, substantially as described.

4. The improved metallic fencing-strip having V-shaped notches at intervals along the .edges intermediately and terminating at the intact inner walls of longitudinal slits at the bottom of the notches, substantially as described.

5. The improved metallic fencing-strip having V-shaped cut notches at intervals along the edges intermediately and terminating at the inner intact. walls of the longitudinal slits at the bottom of the notches and. being corrugated sidewise, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 5th day of March, 1892.
